Thank you Alan,
Yes, I remember you mentioning that before.? While I do try to make sure that everything is well grounded to a copper busbar under the operating bench (even the computer tower), there is so much equipment here all interconnected, it's unlikely to achieve a perfect no-ground-loop situation. . .
Since it's been so long since I last did a Softrock install I'll probably have some more questions.

I DO know that I always used a pair of transformers between my Softrock and the external soundcard.
I never use transformers.
With attention to ground loops any disturbance around the centre may be minimised, even eliminated.
